摘　　要：永磁同步电机通过弱磁控制可实现宽领域调速,其特有的交叉耦合现象使双电流调节器在进行弱磁控制时具有诸多限制。利用交叉耦合现象的单电流弱磁控制策略具有重要研究价值。定交轴单电流调节器弱磁策略存在电机带载能力未得到充分利用的不足。提出一种负载能力最大化的新单电流调节器弱磁控制策略。经仿真验证,该策略能够显著提高永磁同步电机在进行弱磁控制时的最大负载能力。PMSM can adjust speed in a wide field by magnetic weakening control.Its unique cross-coupling makes the dual current regulator have many limitations in magnetic weakening control.The single-current magnetic weakening control strategy using cross-coupling phenomenon has important research value.The weakening strategy of fixed-axis single-current regulator has insufficient utilization of the motor load capacity.A new magnetic weakening control strategy for single current regulator with maximum load capacity was presented.The simulation results show that the strategy can significantly improve the maximum load capacity of PMSM in field weakening control.
